It puts this mic in a different light. I wound up rolling back some of the highs after this mod, just to get a touch more presence and am happy where it sits now. Thanks for checking it out!
Awesome!! Glad it worked out for you! I wound up changing the cap in the one i did in this video as well, just added a touch more top end back and it was good to go!
It was. I may go back and bump that back down to maybe 470pf. Might be a "LITTLE" too dark now. But it was definitely better than the stock. Some guys tune their cars... we tune mics lol
@@meistudiony Hey can you recommend a specific cap to get? I'm getting a P220 for Christmas and I really wanna make the u87 mod to it, without changing anything but the capacitor
Depending on the sound youre going for i could see using the unmodified version of the 240 (if u dont need the patterns) or 420 as both mics are very bright. If youre looking for a little bit warmer or rolled off tone, the mod certainly helps! I have another mod video coming out for another mic that gets that U87 sound at a fraction of the cost, esp if u can find a used mic to start with.
Yeah, i had gone back after this video and upped the value of the cap to put a little more top end back in. (the beauty of this mod is that you can tailor it to your liking) I dont think the piano was really hitting the range where it cut off, so there wasn't much difference.
Nice video showing the modification and its effect well. I, however, prefer the original microphone, especially on the acoustic guitar which loses its high end ring - which is part of the Martin sound - so it sounds dull and loses a bit of harmonic life. Sidebar comment - I am curious why you do not use any sort of vice or jig to hold the microphone steady while you cut and solder, etc. Holding the mic while soldering small bits to the board is substantially more difficult than it needs to be. Trust me, Boobie, it is worth 5 minutes in the workshop to make a simple mic-holding jig making your solder job so much easier and safer. Drive on soldier. JR
I have a jig in the shop... didn't bring it to the kitchen table, so things were a little rough. Not enough space in the shop for the camera and stuff, so i let the wife yell at me for doing things on the table. Hopefully going to be re-arranging the shop in the next few weeks and I'll be able to bring the camera equipment in there. I do agree, the cap i put in for this video was a little much. I did go back and replace it with a 470 and it brought back a little bit of the sparkle without being too much. Sounds really nice on voice. One of the producers in the studio wound up taking it home with him... probably wont be seeing that again any time soon! Thanks for checkin out the video.
audioimprov.com/AudioImprov/Mics/Entries/2013/2/26_AKG_Perception_220.html At the bottom of the page, you can see the negative feedback to the capsule ground. This is the "flattening" part of the circuit. SO its not just a resistor/cap combo, its more built into the feedback part, so my mistake, its not just cut and dry. I thought i had the original schematic somewhere that i got a long time ago, but I can't seem to find it. (was for the Perception 400 i think i had... almost the same circuit... very little has changed from version to version.
Its a signal path cap so just about anything will do. The higher the voltage rating, usually the bigger the cap. You wanna try and keep things smaller to fit. 270 is way more than enough.
HI I OWN A AKG P 22O WHICH IS A CARDIOD . IS IT POSSILE TO MAKE IT INTO AN OMNI DIRECTIONAL . I KNOW IT MIGHT SOUND STUPID BUT JUST FOR MY CURIOUSITY IS IT POSSIBLE.
With that model stock, no, in order to have multiple (including omni) patterns, you need a capsule that has two diaphragms. (Front and back). In theory you could replace the capsule and modify the circuit to do it, but it would a lot of work and with the p420 often being under $200 (and used even cheaper!) youd probably be better off grabbing one of those. Thanks for the message!
Can use any film or ceramic capacitor with the value of your choosing. Depending on how much you go will determine how rolled off the top end gets (from what frequency). Im partial to WIMA capacitors.
The mod can be done with the Perception 400, though i think the capacitor that needs to be changed MAY be in a different place. I'm not 100% sure on that, but I can look into it.
On the board that has the switches for the pad and filter, you should see a bunch of components in two rows of 3. 195 105 105 289 BLANK BLANK If you see that group of components its the second blank or the bottom right most component. Just connect the leads to either side of the existing capacitor.

@@meistudiony yapp ive been here before, but thanks again) ill try firstofall smd 680pf then vima film cap, then install a switch and 2 caps of polystyrene) Ive seen a mod site called mic-parts who write about mod with change a capsule and 1 cap but after reading forum i dropped this idea, the only reason why i want to change a capsule on my perception 220 is golden layer was little bit defected by somebody with brush i think. I want to replace a capsule or membrane and ill take it from perception 200 maybee.
Cant say i disagree. Im thinking of maybe swapping it out for the 470pf to get a little more sparkle in there. Thats the best part of this mod. Literally takes 5 min to do with results instantly recognizable.

I replaced my capsule with one from advanced audio and installed a 480 and it turned out great. I can definitely hear some improvement here. Kudos!
Cool! Which capsule did you go with? (im assuming their AK67 would sound great with this and the mod)
@@meistudiony advanced audio ak67 and yes it does
Big difference, especially on voice and accoustic guitar. I always put a windscreen on to help with the the highs. Definitely trying this mod.
It puts this mic in a different light. I wound up rolling back some of the highs after this mod, just to get a touch more presence and am happy where it sits now. Thanks for checking it out!
I used a 470pf wima cap for mine, and it reallllllly helps alot. Great video!

You’re welcome any time!

@@redcabinacoustic-official that’d be pretty cool. I can head into the city and meet up. Just gimme a heads up, ill be there! ✌️
Just did this mod with a 470pf 50v ceramic capacitor (hope ceramic is alright?) seems to work fine and mic sounds much better.
Ceramic works. As long as the cap is non polarized good to go!
@@meistudiony Hey can you recommend a specific cap to get? I'm getting a P220 for Christmas and I really wanna make the u87 mod to it, without changing anything but the capacitor
@@belairmp3130i wound up swapping the one i put in here for a 470pf. It rolled it off just enough without losing a ton of top end.
@@meistudiony I mean can you provide a link for brand/model of cap because I'm not familiar
@@belairmp3130 i prefer wima. But if u can find a any polystyrene 50v or better will work. I usually get my stuff from mouser.
Hows agk420 for rap music?

it definitely makes a difference...
I think the mod made the acoustic guitar sound a bit muddy. For vocals I think it's fine. Piano, I couldn't tell at all.
Yeah, i had gone back after this video and upped the value of the cap to put a little more top end back in. (the beauty of this mod is that you can tailor it to your liking)
I dont think the piano was really hitting the range where it cut off, so there wasn't much difference.
680 pf, how many watts? are they different in power?
Caps will have voltages on them, not wattage. Anything 50v and above will be fine.

It sounds less cheap, without breaking the bank, i have my p220 modded too 😎
Definitely a cost effective and useful mod. Thanks for checkin it out!
@@meistudiony yeah, brings back to life a beginner mic, really nice
Is this part of a first order low-pass, or??? Do you know the other value(s) in the filter? Thanks
Id have to try and find the resistor value on a schematic. Ill poke around and see if i can find it. But yeah its a simple low pass.
@@meistudiony Thank you, much appreciated!

Is there a requirement for a particular voltage rating for the cap? Or can any be used? I've seen some for 635v and others for 270v.
Its a signal path cap so just about anything will do. The higher the voltage rating, usually the bigger the cap. You wanna try and keep things smaller to fit. 270 is way more than enough.
@@meistudiony thanks!

how many volts the capacitor?
Usually these film caps are crazy voltage. Since its in the signal path anything 63v or higher.
@@meistudiony Great video! Thanks
What should be the voltage of the pf680 capacitor? Is 50v too low? Thank you
50 can work if you can find higher i would just incase. Most of the time the film caps are higher voltage anyway.
Hi. What’s the capacitor name and where can I find it? Thanks!
Can use any film or ceramic capacitor with the value of your choosing. Depending on how much you go will determine how rolled off the top end gets (from what frequency). Im partial to WIMA capacitors.

Que funcion hace ese peqeño capasitor o qe es tengo un akg p220 y akg percepcion 220
El capasitor es parte de un filtro que cambia la respuesta de frecuencia del micrófono en el registro alto.
Hello, please tell me, is your mod suitable for the AKGP400 series...?! Thank you!!!

where is this cap in perception 220&
If im not mistaken the board on the 220 and 420 were the same, just one doesnt have switches. I'll research and get back to you.
